LINT-FLUE.

Specification of Letters Patent.

Patented Oct, 29, 1912.

Application filed February 27, 1912. Serial No. 680,317.

T 0 all whom it may concern:

Be it known that I, JAMES E. CHEESMAN, a citizen of the United States of America, and a resident of South Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Lint-Flues, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to an improvement in lint fiues.

The object of the invention is to improve the construction of lint flues by providing means whereby dirt, leaves, seeds, and other foreign matter freed from the lint will be discharged from the flue without loss of lint.

I will describe my invention in the following specification, and point out the novel features thereof in the appended claims.

In the accompanying drawing: Figure 1 is a longitudinal vertical section through a lint flue embodying the invention. Fig. 2 is a fragmentary vertical section on an enlarged scale of a modified construction.

Like characters of reference designate corresponding parts in all the figures.

As illustrated in the drawing, the flue 10 follows a zigzag course and may be composed of any desired number of turns. A series of horizontal plates 12 are aflixed to vertical side plates 14 and are located so as to provide a space 15 at the opposite ends of consecutive plates thereby affording communication between the horizontal portions of the flue. A downwardly inclined end wall 16 is provided at one end of each horizontal plate 12. These inclined end walls are made of sheet metal plates which may be integral with the plates 12, or they may be made of separate plates. These downwardly inclined walls are located in staggered relation and form the upper port-ions of the bends in the flue.

The lower portions of the bends in the flue are formed by screens 18 which are inclined oppositely to the walls 16 and extend from the lower edges of said walls to a point just below the plane of next horizontal plate 12, but separated from the next inclined end wall 16 by a space or opening 20. The screens 18 may be provided at their lower edges with angle brackets 22 which are adapted to be removably held in clips 24 is provided at its lower end with an inlet 26 and at its upper end with an out-let 28, thereby providing for the passage of air under pressure therethrough.

Adjacent to each bend in the flue is a dead air space 30 into which dust and lighter particles of dirt pass through the screens 18 while the heavier extraneous matter such as sand, leaves, seeds and other foreign matter removed from the lint is discharged through the spaces 20. The lint is blown through the turns in the fine and is deflected by the inclined reticulated end walls 18 and the inclined solid walls 16. The lower edges of the screens 18 being below the planes of the horizontal plates 12, prevent the lint from being blown down into the dead air space, but the other matter being heavier than the lint drops through the openings 20.

The vertical wall of each triangular space 30 may be formed by a hinged door 32 extending entirely across said space as shown in Fig. 1, or it may be composed partly of a stationary plate 3% and partly by a door 36, as shown in Fig. 2. The outer vertical end wall 40 of the casing inclosing the flue is preferably in the form of a hinged door.

This peculiar construction is especially advantageous as the lint becomes more thoroughly cleaned than it does in passing through fiues as heretofore constructed and as the heavier particles of refuse have a free outlet and do not clog up the screens.

What I claim is:

1. A lint flue, comprising a plurality of horizontal sections connected to form a zig zag path, a reticulated inclined wall at one end of each horizontal section, the lower edge of said reticulated wall being below the plane of the bottom of the horizontal flue section and separated therefrom to provide an opening through which foreign matter separated from the lint may be discharged, and a chamber producing a dead air space communicating with said opening.

2. A lint flue comprising vertical side walls, a plurality of horizontal sheet metal plates aflixed to said side walls providing a series of horizontal passages or flue sections, said horizontal plates being so positioned as to provide a space at alternate ends of said sections to produce a zigzag flue through which air under pressure may be forced, downwardly inclined sheet metal plates forming the upper portions of the ends of matter separated from the lint may be discharged, and a chamber contalnlng a dead air space communlcating W1th said openlngi JAMES E. CHEESMAN.

the bends in the flue, and upwardly inclined screens forming the lower portions of the ends of the bends in the flue, the lower edges of said screens being below the planes of the contiguous horizontal plates and separated Witnesses: from the corresponding 1ncl1ned plates to F. GRAVES, provide an openlng through whlch foreign Gr. QUIMBY.
